The Analysis of Kinetics Characteristics of Anammox:a Review
Anaerobic ammonia oxidation(anammox)is one of the most efficient techniques to dispose of sewage ammonia nitrogen and nitrite nitrogen within a reactor.However,in wastewater treatment,anammox bacteria are low growth rate and sensitivity to environmental factors that make the reaction conditions are variable and unstable.In this way,the study of the ki-netics and modeling can be a valuable tool to better understand and use deammonification technology more efficiently.In this paper,the inhibition,recovery and process kinetics models of anammox were reviewed,and the modified Boltzmann mod-el was widely used to describe the recovery performance of anammox after inhibition,and the kinetic processes of different anammox reactors was deeply discussed,it was considered that the Grau second-order model and modified Stover-Kincannon model were the most appropriate and shareable reactor-kinetic models for different anammox configurations.This review plays an important role in environmental factors regulation and the optimization design of anammox reactor.
